A thug who shot at a pack of suspected drug dealers he was trying to rob at a Lower East Side housing project yesterday took a dive into the East River after being chased by an angry mob and cops, witnesses said.

The suspect, a man in his 30s, and two accomplices were robbing the victims at 5:30 p.m. in the Smith Houses at Catherine Slip and Cherry Street when he fired several shots.

One shot lodged in the door of a nearby apartment, but no one was injured in the fusillade.

The gunman took off, but a group of 15 people, possibly including the robbery victims, gave chase as he fled the building.

About a dozen cops joined in, trapping him at the shoreline.

“He jumped into the water like superman,” said a witness.

But NYPD divers surrounded him and forced him to surrender. Charges were pending. The other suspects fled.
